WINDMILL-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 637,736, dated November 21, 1899.

Application filed May 16,1899. Serial No. 717,083. (No model.)

To all whom t may concern.-

Be it known that I, ALBERT HRIssoN, a citizen of France, residing at Paris, France, have invented certain new and useful Improvements in Windmill-Regulators,of which the following is a specification.

This invention relates to windmills designed for working a pump; and the chief object of the invention is to provide new and improved means for varying the strokes of the pump-piston as the velocity of the wind increases and diminishes. This object is accomplished by the mechanism hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure l is a side elevation of sufficient of a windmill and my regulating mechanism to enable the same to be clearly understood. Fig. 2 is a sectional side elevation of the lever for operating the pump-piston. Fig. 3 is a top plan View of the same. Fig. 4 is a detail plan view of the cruciform guide-roll holder and the chain-guide rolls therein. Fig. 5 is a sectional view taken on the line A B, Fig. 4; and Fig. 6 is a detail side view of the regulating-vane and a portion of the vertical spindle on which it is mounted.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings, wherein- The 'letter ce' indicates the tower, b the wheel, and b the connecting-rod, of any desired construction of windmill. The tower is constructed or provided with three horizon tal projecting frames b2, b3, and b4 for pur- `poses which will hereinafter appear.

The outer end of the frame b2 is provided with a suspended axle or shaft s, carrying a grooved pulley s' and constituting the fulcrum-pivot of a horizontally-arranged lever located between the connecting-rodi? and the piston-rod 0L` of a pump. The lever is composed of two parallel side bars 01,2 as, between which aslidefis movable from the point cto the point d of the lever, and conversely. The piston-rod a is pivotally connected to the lever by a clip c, and the lower end of the connecting-rod b is pivotally connected to a part of the slide f, as at f'. The outer end of the frame b3 carries a cruciform guide-roll holder n, (best seen in Figs. 4 and 5,) and the outer end of the frame b4 carries a universal joint la, supportingavertical spindle h. The lower end g of the spindle is attached to a cable or chain fm, passing between guide-rolls n' under the pulley s between the side bars a2 a3 and connected to the slide f. This slide is connected by a chain 0, Fig. 3, withagrooved pulley p, having its axle p' arranged in bearings on the inner end of the slide-carrying lever and connected to one end of a helical spring q', the other end of which is secured t0 a casing q, attached to the lever.

The spindle h carries a regulating-vane fi, composed of a suitable textile or other fabric, secured at its edges to a frame r, having a tube v at its top provided with a pivot-pin u, fitting a bearing or socket t in the upper end of the spindle. The lower end` of the frame fr is connected by a clip or tube y with an arm w, having a sleeve 00 loose on the spindle h. The pivot-pin u and sleeve-x pivotally mount the vane, so that it can turn in a circle on the spindle h as a center, and as the wind acts on the center of the vane the latter will always be placed in correct position. The arm w holds the vane in an inclined plane relative to the vertical spindle h. ing of the spindle from a perpendicular position causes the cable or chain m to pull the slide f toward the point d of the lever, While the spring q' tends to pull the slide toward the point e of the lever. When the wind is comparatively weak, the spindle h is approximately vertical and the slide j' lies at or near the point e and the strokes of the pump-piston are at the minimum. When the velocity of the wind increases, the spindle h, acted on by vane if, is shifted out of perpendicularity and the chain m pulls the slide f toward the point d, thereby increasing the strokes of the pumppiston. The variations in the velocity of the wind cause the slide to move from e to d or conversely, and obviously the strokes of the pump-piston are thereby increased or diminished.

As the lever is very heavy and its weight cooperates with that of the connecting-rod 1J and with the pressure of the water on the pump-piston, the mill would ordinarily be difficult to start, because it rests, when the wind is weak, where the pum p-piston is at the half of its upstroke, at which instant the re- The shiftl sistance isthe greatest. Itis therefore advis-Y able to proyidethe mill with devices for re-Y ducing the strainjrequired to put the mill in rotation when it-is in the position` stated. These 4preferably consist of .long springs z,

`fixed at their upper ends to thetower and attheir lower ends to theconnecting-rod b. The springs are capable of exerting on the connecting-rod b a pull equal to one-half thepower necessary to set the mill in motion when4 the slidefis at the point c.

Having thusd-escribed my invention, what I claim i's- Y l. The combination with a windmill having a connecting-rod, and a piston-rod, of a pivoted lever connected with the piston-rod, a slide movable longitudinally on the lever and connected with said connectingrod, a

lregulating-vane, and'devices connecting the Vane with the slide to automatically shift the latter on the lever, substantially as described.

2. The combination with a Windmill having a connecting-rod, and a pump-piston, of a pivoted lever connected with the piston-rod,

a slide movable longitudinally on the lever and connected 'with the connectin g-rod, a regulating-vane, connections between the vane and the slide for automatically shifting the latter in one direction, and means for moving the slidein theN opposite direction, substantially .as described.

3. The combination with a windmill'hav- `ing a connecting-rod, and a piston-rod, of a pivoted lever connected with the piston-rod, apslide movable longitudinally on the lever and connected with the connecting-rod@ reguthe latter `in one direction, and means for moving the slide inthe `opposite direction, substantially as described.

In testimony whereof I have hereunto set -my hand in presence of ytwo subscribing witnesses.

ALBERT HERISSON.
